This invention-relates to the cutting and sncceedi-ng paper at the moment folding cylindersof a folder for newspaper the latter, after which both *rdf 'cutting are `,carr,ied

The principal objects of this invention are to provide a newarrangernent of the cutting cutting'offY of the edge paper when the second is out, in collecting, and the production of waste'commonly known as sauerkraut 1s avoided; to provide means for accomplishing this result by cutting long and" short ywhich 'they are tuckedinto a pair of 'folding rollers rbyva suitab'lefold'ing blade. Since vthe first paper is already out at 'its'leading edge, when the latter is'made to register with the leading edge offthe there is danger of a certain portion f that` edge being *out od from the paper when .the second cut is imade, thereby producing waste strips, commonly known as Sauerkraut. y

' n the form of the invention 4shownon the first two' sheets,l the `cutting cylinder V 10 has the usual relation tothefolding cylinderlil, the latter having a rubber 12 forireceiving the cutting blade, but in this lcase this rubber 'i's'provided with two groovesl 13 instead ,of 'one' as'usual, the purposeof which will appear ternate sheet willfbe cut vlonger than the previous one,v or by placing `two 4cutting knives on the argerv or foldingcylinder so related to leach-nther as to `divide the circumference unevenflyinto two parts, rand to provide means for operating'these partsgpartioularly the shifting knife in anaccurate and positive manner. A"lhe'invent'ion also' involves l improvements in ldetails Vof construction and combinations of parts as will appear. Y Reference is to lbe had to the -ing drawings, in which 1 Fig.' 1 is an end view partly in section/of a Vcutting cylinder showing its v'relation tothe adjacent .folding cylinderand constructed 'in later.' n For vthe purpose ofV cutting long and short sheets alternately -I place'thecutting knife 11i -in a knife vbox 15 inthe c;V linder 10. lThis `knife boX is located in a recesszlfr in this .cylin- `der and mounted on a pivotstud'll? near the centerso that it canswing from the .position ,shownin Fig. l'back to "a positionin which the opposite side of the knife box accompanythe opposite side ofthe recess.y Itfwi'll be noticed that the knife 14 is one of-gthe grooves lginA Fig. 2 is a sectional view'ofthe'same on the broken. line QZof Fig. 1; v. v

'In the conventional printing 'pressv lthe papers that had been-printed and associated 't over the former are cut into sheets between invention applied a circumference of one page 'carrying'the' cutting' knife and the other has -a'circumference of two pages carrying Vthe cutting rubbers. When it is desired to collect the two adjacent papers' 'on top'of one another, the first is wrapped completely 4around .the small cutting cylinder and is associated'with the plished in the following manner: At Athe end Aof the knife vboxY is a projecting lug 20.7v V'llhis engagesin a radial slot21 in aring 22 which is mounted around .the shaftof the .cutting cylinder atfthat end, ybut is lcapable ofindependent oscillating motion thereon. This 'motion imparted to theringby fthe action.

extending from the outside toward the centerand tangent to a substantially central circle.` ln other words, they diverge fromradial po-` sition. The roller rides in the'jpath of a`V cam 29.-V This'is the pin rod cain and actuates the pin rod to reciprocate the pins 31 through an arm 32 on this rod. The arm 32 has `a roll 33 also engaging inthe cam29 as usual.

; lt will be understood that an eccentrically mounted shaft 35 is provided with two gears 36and 37 which can he moved into-and out of 38 and 40 by the eccentric 41,6., r)The larger of these gears meshes with k39 of thecutting cylinder. The smaller gear 37 meshes with the gear 40, carriedby a bushing 41 free on the shaft39.` The hub of the gea-r '40 and the 'cam.29. are fixed and are shown as integral.

This kgear-Oie larger than the gear 37 and the gear '36 is larger than the gear 33 as shown. The gear ratio is such that for each two rotations of the shaft 39 there will be one 29.. The gearing shown is' conventional.

from the cylinder during the cylinder and withdraw during the' secthe cylinder tobe picked off by similarpins on the folding cylinder as usual. Iutilize the cam 29 of the pin motion to impart the oscillating motion .through the crank 23 to rock the'knife boX 15 back andforth at each alternate 1 revolution `of the cutting cylinder.

v Therefore, on the first rotation of the cutting cylinder the sheetgoing aroundit will be cutat the point indicated hy the position of 1. On the next rotation it will be cut-at; the other groove 13, at which Vpeint tlief'knife will be locatedat that time by the means above mentioned. f rlherefore, every second sheet will be longer -thanthe with the first wrapped around the cylinder i 10and associated with thev succeeding paperv at the moment of cutting the latter, without sheet.

The invention also can be carried out in the form shownyin Fig. 5, in which the mechaynism is somewhat simpler, and involves the use of two knives-414 on the folding cylinder 11 and the cutting rubber 42 on the cutting grOQveS 43 ,at adistance apart and the .two

point alongV the circumference,

`ln this way two adjacent papers will becollected ontop ofone another ycutting cylinder, of a This rubberl also has .twov

knives 44e are placedy out of diametrical alignment with each other. ln other words there is awider space between them circumferentially on one side than on the other. This causes each alternate sheet to be cut slightly longer than the one preceding it-as in the lform shown in Fig. 1. `This eectively eliminates the danger of cutting waste from the preceding sheet as the second knife cuts at a point beyond the previously cut'V edge of the first 'sheet asv inthe other formiSllOwn.

kIt will be seen, therefore, thatwith both of these forms of the invention the same object is accomplished and thewas'te known as Sauerkraut is eiitirely'eliminateth no occasion arising ofV its being cutlfroin the first sheet at any time.fy The mechanism is not unduly expensive in view of the advantages secured.

Although'l have illustrated and-described only two forms. of the invention, ofthe 'fact that changes can be made therein by any person skilled in the art without .departing lfrom the scope of the invention as eX- pressed in the claims.V Therefore, I do not wishwto belimited to the exact forms shown,V but what I do claim is Y 1.-In a folding and cutting couple, the combination lwith a folding cylinder and a cutting cylinder, of
